The American Society of Composers, Authors and Publishers, the performing rights organization, has tallied its latest list of the 25 most popular holiday songs in the last five years. The ASCAP list of the most performed songs on the radio airwaves includes songs that, for the most part, don't relate much to the religious aspect of Christmas. Just as was the case last year, there's an exception to that rule: "Little Drummer Boy," which ranked ninth this time around. The list is below, but ASCAP's news release on the list can be found here.
